Beeper the female House Finch we rescued and raised loved her toys, bells, and swing so I think all birds have a playful side, just we never get to see it.
When she got sick and died a year and a half later we put her toys out in the tree we fed all the wild finches and other birds in. Never recall seeing them playing but being wild they probably were very careful what they did and when.
You lil guy loves you and his playthings, he knows he's safe and can do as he pleases.
